Water Quality Legend

Current Status

Grey means water quality information for the beach is too old (more than 7 days old) to be considered current, or that info is unavailable, or unreliable.

Historical Status

When swimming season is over or when a beach's water quality data has not been updated frequently enough (weekly) it goes into historical status. This means that rather than displaying current data it displays the beach's average water quality for that year.

Green means the beach passed water quality tests 95% of the time or more.

Yellow means the beach passed water quality tests 60-95% of the time.

Red means the beach failed water quality tests 40% of the time or more.

Special Status

We may manually set the status for a specific beach if we have concerns about the sampling protocol, if there is an emergency, if monitoring practices don't exist or have recently changed, or other reasons that render this site "special."

Green means the beach has historically excellent or pristine water quality, but there is no current data.

Red means the water at the site has water quality issues or there is an emergency.

Grey means there is no current water quality information, the beach is under construction, there has been an event that has rendered water quality information unreliable or unavailable.

See the beach description for more information regarding their special status.

This status is based on the latest sample, taken on Agosto 27th, 2018. The Swim Guide updates the status of this beach as soon as test results become available. These results were posted to Swim Guide on at

Vancouver Coastal Health (VCH) monitors the water quality at 50 Coast Garibaldi beaches. Sampling is conducted during the height of swim season (May – September).

VCH follows the Canadian Recreational Water Guidelines. Recreational water is considered safe if the geometric mean result is under 200 E.coli/100mL. Should the geometric mean exceed 200 E.coli/100 mL, or in the event of a known hazard or spill, the Medical Health Officer will make an assessment of the risk to human health. If there is a risk to human health, a warning sign will be posted at the beach stating “This Water is Contaminated and Unsafe for Swimming.” Results are communicated on the Vancouver Coastal Health website (http://www.healthspace.ca/vch). Fraser Riverkeeper updates Swim Guide according to these results, as soon as they become available.

Sampling for this region is dependent on available resources and assistance from local government and other agencies. The VCH employs a ‘risk management approach’ to water quality monitoring of this region, based on the knowledge that the majority of beaches have good to excellent historic water quality in the past.

Local governments or community organizations are encouraged to contact VCH if they would like to collect samples from public beaches in their community. VCH will offer assistance with training, lab services, and the posting of results.

Test results are not consistently posted – we will continue to work with VCH to ensure public safety. Recreational water quality for a beach is determined by E. coli counts from a laboratory approved by the BC Provincial Health Officer for Provincial Drinking Water and Microbiology Testing.

A beach is marked Green when single sample results are under 200 E.coli / 100 ML water.

A beach is marked Red when the results are equal to or above 200 E.coli / 100 ML water.

A beach is marked Grey when there are no current results or there is no available information.
